SUPPLEMENTARY INFORMATION:
Background
The FAA is adopting a new airworthiness directive AD for certain Leonardo S.p.a. Model AB139 and AW139 helicopters. This AD was prompted by reports of spurious inflight disconnections of the automatic flight control system AFCS. This AD
requires updating certain Primus Epic system software, as specified in a European Aviation Safety Agency now European Union Aviation Safety Agency EASA AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective November 1, 2021.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD
as of November 1, 2021.
ADDRESSES: For material incorporated by reference IBR in this AD, contact EASA, Konrad-Adenauer-Ufer 3, 50668

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD
20180002, dated January 4, 2018
EASA AD 20180002 also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for certain Leonardo S.p.a. Model AB139 and AW139 helicopters.
The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to certain Leonardo S.p.a. Model AB139 and AW139 helicopters. The NPRM published in the Federal Register on July 7, 2021 86 FR 35690.
The NPRM was prompted by reports of spurious in-flight disconnections of the AFCS. The NPRM proposed to require updating certain Primus Epic system software, as specified in EASA AD
20180002.
The FAA is issuing this AD to address spurious degradation or unavailability of the full AFCS. The unsafe condition, if not addressed, could result in temporary impairment of the automated flight aid for control of the helicopter and increase the flightcrews workload.
See EASA AD 20180002 for additional background information.
Discussion of Final Airworthiness Directive Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public.

Examining the AD Docket
Conclusion
You may examine the AD docket at https www.regulations.gov by searching for and locating Docket No.
FAA20210505; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, the EASA AD, any comments received, and other information. The address for Docket Operations is U.S.

The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Except for minor editorial changes, this AD is adopted as proposed in the NPRM.
None of the changes will increase the economic burden on any operator.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these products.
